301 or 302 redirects and how do they impact your SEO?

Before we go on to discuss 301 and 302 redirections and their impact on SEO, let us briefly cover what SEO is.

Introduction

SEO stands for search engine optimization — the practice of ranking higher in unpaid, organic search results. By optimizing content quality, page speed, keyword relevance, and other signals, you increase the likelihood that search engines surface your pages to the right audience.

A few key stats that underscore why this matters:

• Google holds over 91% of the global search engine market as of Q1 2025, according to Statcounter GlobalStats.
• The top five organic results account for over 67% of all clicks, according to Backlinko’s analysis of Google search data (2024).

In this post we focus on one specific phenomenon that directly affects your SEO: 301 and 302 redirects — what they are, how they differ, when to use each, and how they interact with link equity.

What is a 3XX redirect?

When you type a URL into your browser and land on a different URL, that is a redirect. The 3XX range of HTTP status codes tells browsers and search engine crawlers what happened to the original URL and where to go instead.

301 — Moved Permanently. The page has been moved to a new URL and will not return. Search engines transfer the old page’s indexing signals — including link equity — to the new URL.

302 — Found (Moved Temporarily). The page has been moved to a different URL, but the move is temporary. Search engines typically keep the original URL indexed and do not transfer link equity to the destination.

301 vs. 302: Side-by-Side Comparison

Property	301 Redirect	302 Redirect
HTTP status code	301	302
Meaning	Moved permanently	Moved temporarily
Link equity passed?	Yes — full equity transferred	No — equity stays on original URL
Original URL indexed?	No — replaced by destination URL	Yes — original URL remains indexed
Browser cache behaviour	Cached indefinitely	Not cached (re-checked each visit)
Best use case	Permanent URL changes, site migrations, domain changes, HTTP→HTTPS	A/B testing, maintenance redirects, temporary campaigns
SEO risk if misused	Low (when destination is correct)	High if used for permanent moves — equity never transfers

How does a 301 redirect affect SEO?

A 301 redirect is the standard choice for permanent URL changes because it passes full link equity to the new URL. Google confirmed in 2016 that 301 redirects do not cause any PageRank loss — a clarification that corrected older guidance suggesting a small penalty applied. In practice, if you redirect Page A to Page B and both pages have the same content, Page B should rank as effectively as Page A did over time.

There is one important caveat: redirect chains. If URL A redirects to URL B, which then redirects to URL C, the crawl path is longer and Google may not always follow all hops — particularly for sites with large numbers of chained redirects. Keeping redirects as direct as possible (A → C, not A → B → C) is best practice.

How does a 302 redirect affect SEO?

When used correctly, a 302 redirect will not hurt your SEO. Search engines treat it as a temporary signal: the original page stays indexed, and no link equity is transferred to the destination. This is the right behaviour for genuinely temporary moves — maintenance pages, short-term campaigns, or A/B tests.

The common SEO mistake is using a 302 for what is actually a permanent move. Because equity never transfers on a 302, a page that should be a 301 but is implemented as a 302 will not consolidate ranking signals to the new URL — sometimes for months until Google re-evaluates the signal.

How do 301 or 302 redirects from HTTP to HTTPS affect SEO?

According to Google’s official guidance on site migrations, no PageRank is lost when redirecting from HTTP to HTTPS using either a 301 or 302. Google actively encourages the move to HTTPS and provides a small ranking boost to HTTPS pages as a security signal.

For this specific case — HTTP to HTTPS on the same domain with the same content — use a 301. It signals permanence to both browsers and crawlers, ensures the HTTPS version is indexed, and consolidates any existing link equity onto the secure URL.

Other search engines such as Bing also support this behaviour, though their exact implementation details differ from Google’s.

When to use 301 vs. 302: practical guide

Choosing the wrong redirect type is one of the most common technical SEO mistakes. Use this as a quick decision guide:

Use a 301 when:

• You are migrating a site to a new domain
• You are moving HTTP pages to HTTPS
• You are consolidating duplicate URLs (e.g., with and without trailing slash)
• You are retiring an old page and replacing it with a new one
• You are changing a URL slug permanently (e.g., after a rebrand)

Use a 302 when:

• You are running an A/B test and the original URL will return
• You are redirecting to a temporary maintenance or coming-soon page
• You are running a short-term campaign with a temporary landing page
• You need to redirect a user based on location or device, and the original URL remains valid

Tools to audit your current redirects: Screaming Frog SEO Spider, Ahrefs Site Audit, and Google Search Console’s Coverage report all surface redirect chains, redirect loops, and incorrect redirect types.

Drawbacks of redirects

Even correct redirects carry minor costs worth knowing:

• Page load latency. Each redirect adds an HTTP round-trip, which adds latency. For users on high-latency connections or mobile networks, a redirect chain of three or more hops can meaningfully affect load time and Core Web Vitals scores.
• Crawl budget consumption. For large sites, every redirect hop uses crawl budget. Resolving redirect chains to direct hops reduces crawler overhead.
• Caching and link update debt. After a 301, update internal links and any high-value external links (e.g., links in your own email campaigns or social profiles) to point directly to the final URL. Relying indefinitely on redirects for high-traffic URLs is a maintenance liability.

Frequently Asked Questions

Does a 301 redirect lose PageRank or link equity?

No. Google confirmed in 2016 that 301 redirects pass full PageRank to the destination URL. Earlier guidance suggesting a ~15% loss no longer applies. Your destination page inherits the full ranking signals of the original URL, assuming content relevance is maintained.

Will a 302 redirect hurt my SEO?

Not if used correctly. A 302 used for genuinely temporary moves leaves the original URL indexed and does not transfer equity — which is the intended behaviour. The risk is using a 302 for a permanent change: equity never consolidates to the new URL, and the original URL may remain indexed when you want it replaced.

How long does it take Google to process a 301 redirect?

Typically between a few days and a few weeks for most sites, depending on crawl frequency. High-authority pages with frequent crawl cycles can see the destination URL indexed within days. Large-scale migrations can take several months to fully consolidate in Google’s index.

What is a redirect chain, and why does it matter?

A redirect chain occurs when URL A redirects to URL B, which then redirects to URL C (or further). Each extra hop adds latency, consumes crawl budget, and can reduce the reliability of equity consolidation. Best practice is to update all redirects so each source URL points directly to its final destination.

Should I use a 301 or 302 when migrating from HTTP to HTTPS?

Use a 301. The HTTP to HTTPS migration is permanent, and a 301 signals that to both crawlers and browsers. Google’s guidance confirms no PageRank is lost in this specific redirect scenario, and Google gives a small ranking boost to HTTPS pages.

Can I use a 302 redirect for an A/B test?

Yes — a 302 is appropriate for A/B testing because the original URL is intended to remain live. Google also supports this explicitly: as long as you are not cloaking (showing different content to crawlers vs. users) and the test is genuinely temporary, a 302 to a test variant will not harm your SEO.

Conclusion

The rule of thumb is straightforward: use a 301 for permanent moves, a 302 for temporary ones. Both redirect types carry some overhead — latency, crawl budget, link update debt — so the best long-term strategy is to keep URLs stable and avoid redirects where possible. When a redirect is necessary, make it direct (no chains), choose the correct type, and update internal links to point to the final destination URL.
